PAUL TURLUR, OF WATTRELOS, FRANCE.

YARN-DRESSING MACHINE.

Specification of Letters Patent.

Patented Mar. 15, 1910.

Application filed August 30, 1906. Serial No. 382,648.

To all whom it may concern.

-Be it known that I, PAUL TURLUR, a citizen of the French Republic, residing at VVattrelos, in France, have invented certain new and useful Improvements in Yarn-Dressing Machines, of which the following is a specification.

This invention relates to an improved yarn-dressing machine in which hot air un der pressure isused for rapidly and effectively drying the yarn, the heat contained-in the vapor generated being utilized to assistthe drying process.

An example of the invention is illustrated in theannexed drawings, in which Figure 1 is a longitudinal section of the machine, and Fig. 2 a perspective elevation thereof. Figs. 3 and 4 illustrate details of the apparatus, Fig. 3 being a perspective view in section through the regenerator, Fig.- 4 being a perspective view of the first heated air supply chamber. Fig. 5 is a plan view in section of the regenerator.

The machine comprises three main parts, viz: the drying-chambers, the heat-regenerator, and a centrifugal blast-apparatus or compressor.

The yarn passes into the horizontal chamber 2, which is divided into compartments 3 4 5 and 6.. After traversing these compartments the yarn passes overa perforated drum 7 into a chamber 8, which it traverses in the opposite direction, whereupon it passes over'a perforated drum 9 into a chamber 10 located below the chamber 8. From the chamber 10 the yarn passes upward over guide-rollers 11 and 12 and then traverses an inclined chamber 13, from which it passes over a roller 14 into the open air and is then wound on'abeam or drum 140. p

The floor of the chamber 2 is formed by the oblong air heating and distributing box 15 (Fig. 4). The upper face of this box has a pluralityof transverse slits 16 formed with oblique sides and opening into the chamber .2. v The box 15 is also traversed by heating pipes 17 Air forced into the end of the box 15 thus asses over the pipes 17 and escapes at the slits 16 where it impinges on the yarn passing alongthe chamber 2. The farther the air. asses along box 15 before escaping at the slits the higher will be the temperature imparted to it by the pipes 17 and conse quently the yarn is subjected to increased heat as it approaches the farther end of the from the sizing rollers 1 chamber 2. From a box 18 beneath the chamber 8 heated air passes in a similar manner into the chamber 8, but the box 18 is divided into two compartments by a horizontal partition 19, so that the air forced into the box must pass all the heating pipes 17 before it enters the compartment above the partition 19, and thence passes at a high, uniform temperature through the slits in the top of the box 18 into the chamber 8. Below the chamber 10 is a similar air box 20. The air passin from box 20 into the chamber 10 is heated to a less degree than the air in the upper boxes.

The arrangement of the three superposed drying-chambers 2, 8 and 10 allows, .firs'tly, of effecting the progressive drying of the yarn in the manner described, and secondly, of separately discharging the va rs generated in the drying chambers, so t at the wet vapors produced during the first stage of the drying operation are not mixed with the drier vapors produced at the later stages. The roofs of the compartments 3, 1,5 and 6 of box 2 are inclihed and provided with apertures so arranged that the vapors generated in the said compartments flow into an up-take 21 in the manner indicated by arrows in Fig. 1. The vapors generated 1n the chamber 8 traverse the perforated drum 7 and thus have a powerful drying effect on the yarn passing over the said drum; these vapors then flow into an uptake 13. The vapors generated in the chamberlO flow past the drum 7 and also enter the same up-take13. The drum 7 may contain vanes adapted to be rotated in thedirection indicated in Fig. 1 by arrows, in

order to. accelerate the flow of the vapors through the drum and up-take 13, and to increase the force with which these vapors are projected against the yarn; the said vanes'are, however, not essential.

' The drum 9 contains a cylinderv 22 to which hot air is supplied by means of-pipes 23' communicating with the box 18, the said the ' The up-take 21 conducts the'wet vapors to theregenerator 2-5, and a centrifugal fan i 33 connected at 28 to the up-take 13 and at 32 to the air chambers of the regenerator sucks dry gases from the said up-take and heated air from the regenerator, the said gases and air being mixed and conducted or t elike,

co ing metal pip by the delivery-conduit 3a to the boxes 15, i

18 and 20 as shown in Figs. 2 and 3. Allthe vapor from thetwo lower chambers flows through the up-take 13 at 28, and fresh air from outside, entering at 30, flows into the box 32 and is heated by the tubes 26, so that 'the fan sucks simultaneously at both places. The mixture is produced in the tube 35 and between the vanes of the fan 33 (Fig. 3).

The regenerator is provided with a funnel '30 which allows of sucking dry air from the upper part of the work-room, where the tern erature is high, or from above boilers if such are adjacent, or from any chamber or locality containing hot air which is not otherwise utilized. T duced in the dressing machine have in some cases a tem erature of 100' degrees centigrade, and t e heat contained in these'vapors is, in the case of ordinary dressingmachines dissipated in the atmosphere. By causing these vapors to pass through the regen'erator their temperature is lowered by the transfer of heat to dry air sucked This dry air may thus be raised to a temperature of say 80 degrees centigrade without additional consumption of. fuel. air thus sucked through the regenerator and the drier vapors from uptake 13 are further heated by the pipes 17 to the highest temperature to which the yarn can beexposed without injury. The. dressing on the yarn forms a protective coating which renders it possible to use a' higher temperature than would otherwise, be admissible. Superheated steam may, therefore, be used for heating the air, more particularly in view of the fact that the air under pressure is not in contact with the steam-pipes 17 for a sufficient length of time to be raised to the same temperature as' the steam. 1

In the above described construction the heating of the airis performed solely in the drying apparatus itself the air drawn into the regenerator by the fan 33 flowing through the conduitl34 to the boxes 15,18 and 20, in which the pipes 17 heat the air as it circulates between them. If the heat.

ing of the air-is 'erformed outside the drying apparatus, t at is to say if air hwted to the desired temperature is supplied-to the boxes,-the heating may take place in various ways...

. tag. The heat contained in the atom a...

, duced in theidressing machine maybe recovered-in two ways. One method consists in usin a regenerator (Fig. 1) consisting of ane ongated-closed chamber-Qtimontaines 26 through-which-the vapors flow, the-a1r to be heatedbeing sucked through the funnel 30 by the action of the 7 fan 33, and caused by baflies 31 t'o-flow =obliquel between the pipes 26,-by vwhich it is $5 heate i The vapors fiowvfromthe pipes 26 e vapors prothrough the air chambers of the regenerator.

The

progressive drying States is:

senate to the discharge-funnel 27. The construction of this regenerator may, of course, be

modified in various ways. The vapors flowing through the u take 21 may be caused to circulate about t e pipes 26, for. example in the box 25, instead of flowing through the said plpes, whereupon they pass away through the chimney 27 In this case cold, dry air from outside, entering at 30, flows through the pipes 26. Another method of utilizing the heat contained in the vapors consists in directly mixing a portion of the latter with comparatively dry" air. At a temperature of 100 degrees centigrade air is capable of. absorbing 591 grams of watervapor per cubic meter. The gases discharged from the dressing-machine usually contain 10 per cent, say59 grams, of watervapor, and are therefore capable of absorbing more. If, therefore, during each passage ofthe vapor through. the machine the fan sucks in half the total quantity of vapor the other half being directly discharged into the atmosphere, and if the vapor sucked inis mixed with an equal quantity of comparatively dry air containing an average of 10 grams of water-vapor per cubicmeter, the moisture will, after the twentieth passage of the vapors, remain stationary at 20 per cent,

and cannot increase beyond this, as can easily be ascertained by calculation. Since separate up-takes are provided for the wet vaponand the practically dry vapor it is easy to. arrange for the circulation of-the former in the regenerator, for the purpose of heating dry air, which is then mixed with the dry vapor. The up-takes are connected to the rear of the machine, instead of using a single uptake in front, as has hitherto. usually been done, the purpose of the former arrangement being to secure a action.

takes extend from the rear to the front of the machine in order to conduct the vaporcharge of the vapor in accordance with the re ulrements of the drying operation.
